Experimental and modeling activity under the Engine Combustion Network (ECN) has expanded significantly over the last several years. In an effort to coordinate future research related to engine spray combustion, ECN met for its first workshop. ECN1 was held May 13-14, 2011 in Ventura, California, several days prior to the ILASS 2011 Conference. 53 participants from 14 countries attended the workshop, while 16 more accessed the live presentations via webcast.
The workshop addressed experimental and modeling activities at two conditions that have received significant attention: the “Spray A” and “baseline n-heptane” conditions. Multiple laboratories have prepared their facilities to operate at Spray A conditions and have completed characterization measurements of the spray. In addition, over 10 different groups have performed CFD simulations of Spray A and baseline n-heptane conditions. Organizers gathered experimental and modeling results at these conditions and provided side-by-side comparison at the workshop, including a summary and some recommendations for future practices.
Proceedings from the workshop are available to download below. The proceedings include a summary abstract followed by the presentation. When movies were used in the presentation, a .zip file has been made to allow delivery of all of the information.
